BINDER FOR LEAVES.

SPECIFICATION forming part of Letters Patent No. 6uo,975, dated June 21,1898;

Applieation'filed. ul 1,1396. Serial No. 597,578. (amen Be it known that I, FRANK E. ROBINSON, a

citizen of the United States, and a resident of New York, in the county and State of New York, have made certain newand useful Improvements in Binders for Leaves, of which the following is a specification.

My invention is an improvement in binders for securing and holding single leaves, sheets, or blanks such as. are employed for recording commercial orders for goods and similar purposes.

The object of my invention is to provide an inexpensive, durable, and effective binder fororder-blanks which shall be so constructed as to receive and hold any number or varying numbers of leaves, and to further provide means for removing and replacing any single blank without disturbing or-removing any of the other blanks of the series.

I provide a back board or. frame or support about the size of the blanks or leaves to be bound or held, although it may be considerably larger. At or near one edge-say the top edge--I fix two iron rods or posts projecting vertically. I provide a cover, top board, or strip, having holes or perforations through which the rods or posts easily pass-that-is,

so as to permit the said top piece to slide freely on said rods or posts. Upon this top piece,cove r, or strip I place two hinged or pivoted evers. The free or engaging endsof each of these levers is in close proximity to a post or red, so that when moved in one direction the lever is tilted and. its end slides freely along the post, but when moved in the opposite direction the end of the lever takes into the surface of said rod and movement is blocked' I prefer to notch the engagingend of each lever with a notch in the are of curvature corresponding to the surface'of the rod it engages, and I bias the free or engaging end of each lever, so as to normally throw it into contact with the rod. For-this purpose I prefer to employ a sprin of-suitable construction preferably placed under the end of the lever on the opposite side of the fulcrum from the engaging or contact end. The two pivoted lovers are placed on the top board, strip, or cover on suitable bearings outside the two rods or posts. Theblanks employed are perforated with holes corresponding in position and size to the two or more vertical rods above described, and a diverging notch or channel is cut from the edge of the blank leading into such holes, so that by slightly curving, folding, or bending the blank it may be .disen gaged from the rods or posts."

The accompanying drawings illustratemy invention.

Figure 1 is a complete view of my invention. Fig. 2 is a cross-section of Fig. 1 in a line drawn through the vertical rods. Fig.

3 shows the arrangement of notches in the 1 blanks to be employed.

B is a backboard of wood or card. Rods R R, which may be of any metal and either round or polygonal, as shown, are fixed, as at f, to the board B. p

C is a top board, support, or cover. Across the top edge there extends a plate of metal P, riveted to the board 0, as at 'r. The board 0 and strip Pare perforated with holes corresponding in shape, size, and position to the rods B, so that the cover 0 may slide freely on the rods. On the strip P are supported two levers pivoted or' hinged, as at I, and having th'eirends notched to conformto the outline of the posts or rods B, as shown at a. Springs S throw the ends ofthese levers into contact with the posts or rods R, and while the levers slide downward in contact with the rods R the reverse movement is blocked by reason of the engagement of the ends of the levers with the rods R.

It is desirable to be able to release, remove, and replace any single leaf or sheet of a series, and for this purpose I slot or notch the edges of the leaves with cuts a, which diverge from poin tsorperforations in the sheets corresponding in position to the position of contaetlecat'ed neei ithe ena 0f strin, a

substantially as and 01} the pu'rpqse described. v I i FRANK E. ROBINSON; Witnesses: 7
